As the world's population hits seven million, freshwater resources are even more threatened by the effects of climate change. At the third "Changing Planet" Town Hall, held at Arizona State University, NBC News Chief Environmental Correspondent Anne Thompson interviews a panel of experts on how we can develop better, more sustainable water practices. Featured are Bill Richardson, Former Governor of New Mexico, Grady Gammage, Jr., Senior Sustainability Scholar at the Morrison Institute for Public Policy, Heidi Cullen, correspondent for Climate Central and Pat Mulroy, General Manager of the Southern Nevada Water Authority. This "Changing Planet" Town Hall was produced in partnership with the National Science Foundation.

In 2001, Drs. Bill Bradshaw and Christina Holzapfel at the University of Oregon became the first scientists to prove that recent global climate change is causing genetic adaptation in certain organisms. Their research over the past 30 years has focused on the pitcher plan mosquito and its changing response to the length of sunlight in a day.

The wine industry is a multi-billion-dollar-a-year industry, but it could be in serious danger due to climate change. Scientists Grant Cramer and Anne Fennell are studying how different grape varieties respond to harsher conditions such as drought and spring frost. Their research could help vineyards and other farms that grow grape products, such as raisins, juice and fresh fruit. Changing Planet is produced in partnership with the National Science Foundation.

Millions of pine trees are dying in western North America, all due to a beetle about the size of a grain of rice. The mountain pine beetle uses pheromones, a chemical that attracts other mountain pine beetles, to successfully overwhelm a tree's defenses and kill it. Dr. Ken Raffa at the University of Wisconsin-Madison and Dr. Gary Blomquist at the University of Nevada, Reno are studying the beetle and how climate change is impacting its spread.

Dr. Joy Ward at the University of Kansas is looking at how rising levels of carbon dioxide in the atmosphere may be impacting trees around the world and even causing them to adapt. By looking at ancient tree specimens from the Ice Age, Ward is able to see how trees in the past have adapted, helping her understand how trees may adapt today and in the future.

Because of a warming atmosphere, permafrost -- the frozen ground that covers the top of the world -- has been thawing rapidly over the last three decades. But there is cause for concern beyond the far north, because the carbon released from thawing permafrost could raise global temeratures even higher.
